When operating with Class I or II leaks, continue to check fluid level more often
than required in the PMCS. Parts without fluid will stop working and/or cause
Class III leaks should be reported to your supervisor or unit maintenance.
If the equipment must be kept in continuous operation, check and service only
those items that can be checked and serviced without disturbing operation.
